Both the club and the Brazilian forward himself have confirmed he will formally put pen to paper on Monday and join the Camp Nou giants this summer

Barcelona has officially confirmed it has reached a deal with Santos to sign Brazilian star Neymar, who will sign a five-year contract with the club on Monday.

The forward himself also broke the news through his Instagram and Facebook accounts and revealed his appearance against Flamengo on Sunday would be his last for his boyhood club.

"FC Barcelona and Santos have agreed to terms for Neymar da Silva Santos Junior. The Brazilian forward will don the Blaugrana strip for the next five seasons," a Barcelona statement read.

The transfer deal for Neymar, who opted to join Barca over Real Madrid, will be worth around 28 million euros, with the player's deal tying him to the Camp Nou club until the summer of 2018.

The Brazil international will earn around 7m euros a year at Barcelona, which has also agreed to play two friendly matches against Santos - one at home and another away - as part of the deal.

"It is not going to hold out until Monday. My family and friends already know my decision. On Monday, I will sign a contract with Barcelona," Neymar said on Instagram.

"I want to thank the fans of Santos for these incredible nine years. My feeling for the club and the fans will never change. It is eternal! Only a club like Santos FC could give me everything I experienced on and off the field. I thank the wonderful Peixe fans who supported me even in the most difficult moments.

“I insisted on playing my last match, tomorrow, in Brasília. I want to have the chance to walk into the pitch once more, wearing this shirt and hearing the fans sing my name. Titles, goals, dribbling, celebrations and songs that fans created for me will be forever in my heart. This is a different moment for me. I'm sad (because of the goodbye) and happy (to have a new challenge).”

Neymar's contract with Santos had been due to run until next summer's World Cup but he was always widely expected to move to La Liga this year so the club could secure a transfer fee for his services.

The 21-year-old has been named in the Brazil squad for the Confederations Cup tournament in June, after which he will link up with his new Barca teammates ahead of next season.
